A student said to his master: "You teach me fighting, but you talk about peace. How do you reconcile the two?" The master replied: "It is better to be a warrior in a garden than to be a gardener in a war." - unknown/Chinese

Edit - Ene you mentioned somewhere that you are an INFJ and was asking for feedback regarding the enneagram type. I would have guessed INFP over INFJ (mind you I haven't read that many posts of you). But now that you have typed yourself as 5w4, I'm beginning to see a bit of INFJ in you.

There is another member called @cascadeco who is also a INFJ 5w4 who likes physical activities and kind of communicates like you. (I know you like physical activities and your occupation is related to both physical and imaginative.)

If that is true, I wonder if So/Sp could mess with somebody's F-ness? It is, after all, the rough opposite...

If you'd said sp/so, then the answer would have been possibly. From 16types:

Self-preservation instinct focus on practical and pragmatic matters may be easily confused for Jungian Sensing and Thinking. Income and salary concerns, planning, scheduling, budgeting, can be mistaken for extraverted logic, Te. SP/SX's interest in things that serve as common denominators of life (family, food, prices, TV shows, etc.) and can be mistaken for them being a Sensing type.

So- doms are more likely to be mistaken for extroverts and Fe users, accoring to the same source.
